SENSOR ADDRESS
Here, the StartSlot can also be set manually: in the transmitter, the " JetCat V10" sensor is also
to be set manually at the corresponding slot address (1…18).
2.5.4.2
FUEL-CONSUMPT.
The VSpeak ECU converter can calculate the current fuel flow (F-FLOW) and the fuel
consumption (FUEL) on the basis of the turbine pump voltage. The required parameters can be
adjusted in this menu.
In points 20 and 21: "FL / 1.5V" the fuel flow in ml/min is associated to the pump voltage of
1.5V. Same at "FL / 3.0V" but to 3.0V.
Tips for determining the fuel flow rate can be found in the appendix of these operating
instructions.
22:TAXI TANK
For models where a taxi tank is plugged into the main tank until the model is lifted off, set
"Taxi = ON". If the turbine is "Running", then when THROTTLE = 80% is exceeded for the
second time
, the FUEL will "reset", ie the consumed FUEL is only once set to "0" again at
this time.
2.5.4.3
ALARM
In the Futaba system alarms can be generated according to the set alarm thresholds for each
value in the transmitter or the Telemetry Box. In the sensors itself no alarms can be set. This is
for most sensor data also sufficient, such as an alarm for monitoring the EGT temperature.
But for alerting the rotation speed monitoring the VSpeak ECU converter for Futaba offers the
following option:
Rotation speed monitoring
Thus, the speed is displayed correctly, you have to set the speed display to type: magnet
and gear ratio 1.
31: RPM
value range:
OFF, 20.000 ….99.900 rpm
step size: 100 rpm
1. value = OFF
The current speed is transfer 1 : 1.
If an alert threshold of for example <30,000 rpm is programmed in the transmitter, then the
alarm is already active at the switching on of the turbine and the receiving system. That's
why:
2. value = 35.000rpm (as example)
The speed is transferred to the transmitter divided by a factor of 10. Only in the alarm case,
speeds less than the set value are transferred 1 : 1. The alarm is active AFTER exceeding the
set value.
In the example, the speed monitoring is only activated after exceeding 35,000 rpm. The
actual 40.000rpm are displayed on the transmitter as 4.000rpm, 35,100 as 3.510rpm. If speed
decreases further then 35.000rpm speed transfer is 1 : 1. Has the transmitter an alarm
threshold set to > 15.000rpm, the alarm starts. If turbine speed falls below 15.000rpm - for
example, turbine was switched off, then the alarm stops because speed is now less than the
alarm threshold value.
